SPECIFICATION forming part of Letters Patent `No. 268,902, dated December 12,1882.

` Application filed May G, 1882. (Model.)

To all whom it may concern:

Beit known that I, M. L. JACQUEMIN, ot' Oonncil Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Perpetual Galendars; and I do hereby declare that the following is a full, clear, and exact description ot' the same, reference being had to the accompanyingdrawings,forminga part ofthis specitication.

This invention relates to improvements in perpetual calendars adapted to be operated by clock mechanism, or, on a smaller scale,by watches, or by any kind of time-keeper, Whereby an eflcient and reliable calendar is provided for automatically making the weekly and monthly changes, for showing` the names and numbers of the months, for making the changes for the different numbers of days in the months and the leap-year changes, and for showing the number of the quadrennial year,

and the nature of the invention consists in the employment of mechanism substantially as hereinafter fully described.

1n the accompanying drawings, Figure 1 is a front elevation of the dial of the calendar. Fig. 2 is an enlarged vertical section of my calendar. Fig.'3 is a horizontal section, and Fig. 4 is au enlarged plan view with the dial removed. Fig. 5 is a detailed plan view ot' the date-wheel land its cam. Fig. 6 is a side elevation of my calendar, also with the dial removed. Fig. 7 is a side view ot' the dateerating lever, the index-carrier, and the frame or support upon which they are supported. Fig. 8 is aside view of the combined day or week ratchet and datewheel operating pawls. Fig. 9 is also a side vienr of the week-ratchetholding pawl. Fig. l() is a similar siew-ot' the combined rider and carrier,having the quadrennial-wheel-operating pawl. Fig. l1 is an inverted plan view of the date-wheel and its cam. Figs. 12, 13, and 14 are detail views of the day or week ratchet, the month-pinion, and the qnadrennial wheel and dial, respectively.

In carrying out my invention l employ a frame, 5, suitably fastened at l to aback plate, L, itself fastened to a frame inclosing` the several parts ot' my calendar, and having arranged therein the dial A'. Upon this dial are arranged in a circle the numerals from l to 31, indicative of the number of daysin one of the longest months; and within this circle is disposed in a lesser circle the names or abbreviations of the months in a year, preferably arranged to coincide with the arrangement of the numerals denoting the hours of a day, marked on the clock, watch, or 'other timekeeper dial. The names or abbreviations of the days of the week are arranged on the dial in a circle eccentric to and within and near the top ot' the circle of the names of the months of the `year. The frame 5 has preferably secured to it at B the shaft A, upon which is sleeved, as at F, the date pointer or index G, and upon the sleeve E of the pointer or index Gr is sleeved, as at H, the month-pinion D, while upon the sleeve H of the monthpiniou is sleeved, so as to turn with it, the month pointer or index I.

O is the toothed date-wheel,secured upon a hub of the date-pointer sleeve F. The datewheel C has spokes c radiating from a disk whose diameter is greater than that of the drum of the sleeve F, to which it is secured, said disk having a portion of its surface removed or notched, as at c', causing the extension inward of one side of one of its spokes, as at c2, while from this notch the said disk is provided with a downward-inclined tongue or cam, q, all being disposed within the diameter of the said disk.

Upon and at the opposite end ofthe hub of Vthe wheel O is affixed a cam, J, the face of which describes thel curve or segmentof a circle that increases in diameter as it recedes from said hub to the point of said cani or segment, the purpose ot' which will be explained hereinafter.v The cam J is provided upon op posite sides with the projections or stndsf z, one arranged contiguous to the month-pinion D, and the other,j", at a point where it will conditionally arrest further movement of the carrier, presently described, when the projection z shall have pushed the toeot' the carrier, with its projection, out of engagement with the month-pinion.

7 is the rider, which consists ot' a curved bar having a right-angled projection, b', at its upper end, which rides up on the upper surface of a segmental arm ot' the frame 5, said IOC rider having in its concavity and projecting from its opposite side a projection or stud, or, and being pivoted at its lower end to the carrier 6, eccentrically to the pivotal point of the carrier. The rider has an arm, b, at its lower end, to which areeonnected the lower ends of two springs, a t, the opposite end of spring a being connected to the combined day or week ratchet and date-wheel operating pawls 9 and l0, and that of the spring t to the index or pointer-carrier S at u. The carrier 6 carries a spring pawl, c', which engages with and moves the quadrennial toothed wheel P. It also has two arms, one being provided with a projection, g', and the other provided with a toe, c', and close to the latter, with a projection, d', the function of which will be apparent hereinafter. The projection by ofthe rider7 is adapted to enter the slot or notch w of frame 5, and to strike the index-carrier S atr, as will be seen in connection with the operation of my invention.

ll is a third-class lever pivoted upon the central shaft, A, and connected by the rod Z, or other suitable medium, to the operating mechanism of the clock, watch, or other timekeeper. The upper'end of the elbow ot' the lever 11 is guided against the frame 5, and limited in its forward stroke or movement, as against the action ofthe spring a, by the stop a2 of said frame. The lever 11 is connected at U to the pawl 9, which has atooth, W, engaging with the day or week ratchet M, suitably hung upon an axis, K, xed to the plate 5. The outer or free end of the pawl 9 has a weight to hold it by gravity in engagement with the ratchetM. At the same point where the lever 1l is connected tothe pawl9 it (the latter) is connected to a gravity or weighted pawl, l0, which engages with and operates the date-wheel 0.

13 is a pawl sleeved upon the quadrennial wheel stud O, which is acted upon by a spring, d, connected to a stud, e, thereof, and to the frame 5 atf, said pawl or detent engaging with and preventing` the reaction ofthe date-wheel().

S is the index or pointer carrier for registering the number of days in each month, sleeved upon the shaft A, and having attached thereto at u, as before intimated, a spring, t. The upper end of the carrier 8 has attached to it a pointer or index, S, arranged to move on the face ot' the dial A', the means connecting the pointerorindex to the carrier being permitted to pass through and move in a curved slot, T, in the dial, said slot coinciding with the segment of the circle of dates of the month from and including the number 28 to 31. The carrier 8'has a rearward downward-projecting spring-pawl or detent, 8, and an arm arranged on the same side thereof and carrying a curved tootli,k,the former having atits extreme lower end two projections or studs, pp', arranged on opposite sides thereof and adapted, one, p', to enter any one ot' a seriesof notches, n, made in the rear edge ofthe frame 5, and designated individually n n2 ai n4, while the proieetion p' will, when the projection p is sprung out of its notch n., enter the notch or opening c of the date-wheel C, as more clearly hereinafter pointed out. The curved tooth 7c is designed to enter notches or slots in the quadrcunial wheel P, as hereinafter desciibed.

P is the toothed quadrennial wheel, turning or sleeved upon the l.stud Oof the plate or frame 5, and having upon its face a calendar, Q, as seen more fully iu Fig. 14. This calendar has upon its face a circle of figures which is di vided into four subdivisions or sections, indicated by the numerals l, 2, and 3, and the words leap year,"7 each subdivision or' said circle of figures containing the figures l to l2, and covering a registration of twelve months, or one lvear, and the four sections covering, of course, four years. For each month indicated on the calendar Q the wheel is provided with acoincident notch or slot on its periphery, said notches or slots being gaged in depth according to their respective functions. Those notches or slots which stand for the months having thirty days are designated by the letter fi, and those for the months having thirtyone days are designated by the letterj, while those slots` which stand for each of the three Februaries of the quadrennial period having twenty-eight days are denoted by the letter g, and that for the February of leap-year, or the one having twenty-nine days, is denoted bythe letter lL.

Fixed to the quadrennial wheel stud O is a pointer or index, R, registering with the number or figures on the quadrennial wheel-calendar Q.

I will now give a description of the operation of my invention.

Assuming that the pointer or stud Gt of the date-wheel G stands at the number 3l on the dial A', indicating the last day ot' the present month, the next movement of the pawls 9 and 10, actuated by the time-keeper mechanism, will cause the day-ratchet pinion M to move, as they will also the date-wheel U, causing the movement of the hands G N, whereby one will register with the day of the week and the other with the ordinal l on said dial, indicatingjointly the daY and the date'. Simultalneously with the aforesaid operation of parts the month-pinion is moved to denote the incoming month, as are also the pointer or index S,iudicating the numberof days in said month, and the quadrennial wheel P, registering the number ot' the month and indicating leap-year when it occurs. The movement of the hand or pointer I of the month-pinion D and the pointer S ofthe carrier 8 and the quadrennial wheel P, its pointer R being stationary, is effected as follows: The date-wheel cam J baving been brought around, during the sundry movements made by the date-wheel O during the thirty or thirty-one days of the past month, against and caused the outward movement ot' the rider 7, the notch c2 of the wheel C, which ICC IOS

rio

. the action ofthe spring c.

has been brought opposite the stud p of the index-carrier spring-paivl 8a, will permit the stud or tooth p of the said pawl to springont of its notch u ofthe series of notches u iii the frame 5. After the retraction of the tooth p ofthe pawl Sb of the carrier 8 from its notch in the frame 5, and the projection or springing of its stud p into the notch c of the wheel U, the cam J of the latter will escape from the projection .fr of the rider 7, the right-angled projection b` of the rider having in the meantime arrived opposite the notch w in the frame 5. At this juncture the projection z of the cam J will move in contact with and operate the toe c ofthe carrier G, so as to retract its tooth d" from the teeth of the moiith-pinion D, when the said pinion will be permitted to revolve by the action of the wheel P, as presently described. effecting the movement ot its hand I, which will indicate the month on the dial A. After the pinion D, with its pointer or hand` has pei-formed its said function the tooth d' will again spring into the teeth of the pinion D by the action ofthe spring u. Simultaneously With the movement of the toe c of the carrier 6, previous and preparatory to retractingits tooth d from the pinion I), the projection b will be caused to descend the slot w of the frame 5, opposite which it had previously arrived, as before stated, to allow the forward inovementot' the index-carrier 8, with its pawl 8, under the forwardly-pulling action ofthe springt, to enable its pointerS to register with the required figure on the row oftgnres at Ton the dial A. This movemcntofthe.pointer S indicates the number of days in the current month. When the projection z ofthe cam J has escaped from the toe a' of the carrier 6, and upon the tooth d re-enteriiig the teeth ot' the pinion D, the projection b of the rider 7 will spring out of the slot w of the frame 5 under This action or" the projection b will bring it into contact with land cause it to bear against the index-carrier 8 at r until another similar movement as the aforesaid is made. 'Vith the retraction ofthe tooth d ofthe carrier 6 from the month-pinion D the pawl e will, by the movement'thus imparted to the carrier 6, to which said pawl e is connected, be disposed in proper relation to the teeth of the quadrennial wheel P; and, as the said tooth dis again dropped into the teeth ofthe wheel D, cause the movement of the said wheel one tooth, which will impart a like movement to the montli-piiiioii, as and for the purpose above stated, as relates to the month-piiiion. With the movement of the toe a. of the carrier 6, caused by the action of the projection z ot the cam J, the tooth k ot' the springpawl Sa of the indeX-carrier' will be lifted ont ot' its slot or notch in the Wheel P; and upon the return of the tooth d of said toe of the said carrier to the pinion D, the wheel P being moved in the meantime, as above set forth, to piesent the succeeding notch or slot of said wheel to said tooth k, the said tooth l; willagain fall into the succeeding slot or notch ofthe Wheel P, whereby, simultaneously with the indication ofthe day of the week, the date and naine ofthe month, and the number of days in the month, will be registered the number ot' the. month and when leap-year occurs in the forty-eight months designated upon the calendar Q by the pointer 1t of the quadrennial-wheel P.

lt will have been observed that with the lifting of the tooth r ont of its coincident slot or notch of the wheel P the tooth p' of the pawl 8f is permitted to spring out ot' its coin. cident notch in the plate 5,'the notch c of the wheel C being brought opposite the said tooth p andthe stud p ofthe pawlS at tha'tinstant, and that after the tooth k of the pawl 8lm has been again projected into another or succeeding` slot or notch ot the wheel P the tongue q ofthe dish of the wheel G will press the tooth pf into one ot' the notches n of the frame 5,

the projection g on the carrier when the opl erative mechanism shall fail to operate, to hold the carrier 6 as against further movement.

The foregoing construction and arrangement ot` parts is such as to permit settitig the indicator-hands by turning` them forward, in substantially similar manner to the setting of an ordinary clock, thus ai'ording conveniences of immediate adjustment of the calendar to proper day and date after any possible stoppage of the. actuating time piece mechanism connected to lever ll by rod V.

Having thus fully described my invention, I claim and desire to secure by Letters Patent- 1. Thecombinationotthemonth-pinionDand its pointer G, week-ratchetl M and its pointer N, click-lever 1l, and clicks 9 and 10, substantially as specified. j
